I'm so glad that the dog didn't hurt you bad, I would've been scared! I totally understand your fustration and anger, and don't worry, you have every right not to be lady like when the dog just bit you out of no where! I wonder how many other times this dog has done something like that and the owner used the same excuse "oh he's never showed aggression before"
If this person keeps taking his dog out, unmuzzled, unfortunatly it CAN really hurt someone some day, and the owner will be saying the same thing. Why do people think they can just allow an aggressive dog out among the public and not worry about it! It's not that hard!
